Modern Humans And Neanderthal Essay

Decent Essays

1. Introduction

The relationship between modern humans and Neanderthals has been argued for a long time. There are two main different ideas that explain the origin of modern humans, the Out of Africa theory and the Multiregional evolution theory. The first theory has been largely accepted by the scientist community, however, the issue is not a simple one, and a final theory has not been postulated yet. Different disciplines have provided evidences to reconstruct the Neanderthals history. In particular a great improvement comes from bio-archaeology evidences, provided by DNA and Isotope analysis.
The aim of this essay is to understand the relationship between the Neanderthals and modern humans, particularly focusing on the development of theories about the human evolution during the last 20 years.

2. Evolution theories

The Multiregional Continuity Model argued that after Home erectus …show more content…

• The different in modern humans, namely regional variants, are due to natural selection in different regional populations.
• Some level of gene flow between geographically different populations stopped evolving in different species.
• The evolution of Homo sapiens was a phenomenon that occurred in the entire World where human lived.
On the other hand, the Out of Africa Model supports the idea that modern humans evolved relatively recently in Africa, and then spread out into Eurasia and slowly took over all populations that had developed from Homo erectus, includes Neanderthals (Stringer & McKie, 1996). The main arguments that support the theory are:
• After the Homo erectus migrated out of Africa, different populations became independent between each other and evolved in separate species, like the Neanderthals.
• The modern humans completely developed in one area, probably Africa.
• There was not interbreeding between other human populations such as with
